Bio:Ex-girlfriend of Bruce Wayne. They went out for 6 dates but Bruce refused to go any further and ended the relationship. On a cruise with her friend, the ship was robbed by gangsters who shot Una and her friend, but Una survived (despite a fist-sized hole completely through her head) because she suffered from Dandy-Walker Syndrome, a condition in which a large part of the brain is physically missing. Traumatised, she became a super-villain. She also attacked Vicki Vale.
